Communication device and method for packet communications in a contention-free period
First Claim
Patent Images
1. A communication device comprising:
- a memory; and
a processor coupled to the memory and configured to;
create a first packet for transmission to an apparatus, the first packet storing last data to be transmitted in a contention-free period assigned to the communication device,create a second packet for transmission to the apparatus,based at least in part on a link quality of a link between the communication device and the apparatus;
determine to which one of the first packet and the second packet first information is to be added, the first information being configured to indicate presence of remaining data to be transmitted in the contention-free period, anddetermine to which one of the first packet and the second packet second information is to be added, the second information being configured to indicate absence of remaining data to be transmitted in the contention-free period,transmit the first packet including at least one of the first information and the second information to the apparatus within the contention-free period, andtransmit the second packet to the apparatus within the contention-free period and after the transmission of the first packet.

Abstract
A communication device includes a memory, and a processor coupled to the memory and configured to transmit a first packet including a first information within a contention-free period assigned to the communication device, the first packet storing last data to be transmitted in the contention-free period, the first information indicating presence of remaining data to be transmitted in the contention-free period, and, after transmit the first packet, to transmit a second packet including a second information within the contention-free period, the second information indicating absence of remaining data to be transmitted in the contention-free period.

10. A communication method for a communication device in a network, the method comprising:
-
creating a first packet for transmission to an apparatus, the first packet storing last data to be transmitted in a contention-free period assigned to the communication device, creating a second packet for transmission to the apparatus, based at least in part on a link quality of a link between the communication device and the apparatus; determining to which one of the first packet and the second packet first information is to be added, the first information being configured to indicate presence of remaining data to be transmitted in the contention-free period, and determining to which one of the first packet and the second packet second information is to be added, the second information being configured to indicate absence of remaining data to be transmitted in the contention-free period, transmitting the first packet including at least one of the first information and the second information to the apparatus within the contention-free period, and transmitting the second packet to the apparatus within the contention-free period and after the transmission of the first packet. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

21. A communication apparatus in a wireless network, the communication apparatus comprising:
-
a memory; and a processor coupled to the memory and configured to; transmit a first packet and a second packet to a device over a wireless link in a contention-free period assigned to the communication apparatus, the second packet being transmitted after transmission of the first packet; and based on a link quality of the wireless link or a power consumption of the communication apparatus, select a first mode or a second mode for transmission of the first packet, wherein in the first mode, the first packet is to be transmitted with a flag indicating that there is no remaining data to be transmitted in the contention-free period, and in the second mode, the first packet is to be transmitted with the flag indicating that there is more remaining data to be transmitted in the contention-free period. - View Dependent Claims (22, 23, 24)
